Description

A kind of landing impact testing machine
Technical field
The present invention relates to engineering detecting equipment, more particularly, to a kind of landing impact testing machine.
Background technique
Impact is a kind of common Mechanics Phenomenon in daily life and engineer application, and it is one that experiment simulation is carried out to it The effective research means of kind, and drop experimental machine is exactly one such important experimental facilities.Drop experiment Machine is made of rack, guide rail, tup and counterweight, lifting device and control device etc..The basic principle is that using freely falling The speed of body, which realizes test specimen, hits load, thus the response of research material and structure under impact loading.When experiment, examination Part is located at guide rail lowest part, and tup and counterweight are located at test specimen top, by control device and lifting device to tup and counterweight into Row is promoted, and is discharged after reaching specified altitude assignment, and tup and counterweight will do the movement of falling object along guide rail later, is finally struck Load is realized on test specimen.
The Chinese patent document that Authorization Notice No. is CN202403989U in the prior art discloses a kind of mechanical baffle-type Secondary pulse capture and restore plastic pipe impact test machine, including Vertical Rack, loaded on Vertical Rack vertical litter, The taper hook baffle that is fixed on vertical litter, is placed on dropping hammer in drop hammer lifting mechanism, pedestal lifting at drop hammer lifting mechanism Device and anti-secondary pulse device.When experiment, by drop hammer lifting mechanism by drop hammer lifting to scheduled elevation, then by falling It hammers release mechanism into shape, is loosened dropping hammer, impact test is carried out to test specimen in gravity freely falling body so that dropping hammer.
The existing generally existing following defect of above-mentioned drop hammer impact testing machine: although the setting of guide rail can be to the cunning dropped hammer Dynamic rail mark is limited, and is fallen so that dropping hammer in vertical direction, but can not overcome the influence of rail friction power;And at present The structures such as the release mechanism dropped hammer mostly uses electromagnetic mechanism to loosen or link up with, bolt, during loosening, unavoidably to dropping hammer The active force for generating non-vertical direction, to the horizontal direction frictional force for generation of dropping hammer, any non-perpendicular active force when such as pulling out bolt It all may cause generation shaking of dropping hammer, generate rigidity friction with the junction of guide rail so as to cause dropping hammer, which is It is unable to measure, so can have an adverse effect to testing result.Therefore, how rail friction is reduced in falling weight impact test The influence of power is that those skilled in the art need to overcome the problems, such as.
Summary of the invention
The object of the present invention is to provide a kind of landing impact testing machines, it is possible to reduce rail friction power tries drop impact The influence tested.
Above-mentioned purpose of the invention has the technical scheme that
A kind of landing impact testing machine including rack and is vertically installed in the guide rail of rack, is slidably connected to falling on guide rail Hammer and drop hammer lifting mechanism, the guide rail be circular rod-shaped configuration, it is described drop hammer to be connected be sheathed on guide rail upper mounting seat, pacify Dress seat is equipped with the location hole worn for guide rail, and the internal diameter of the location hole is greater than the outer diameter of guide rail;The guide rail is for two and right Claim the two sides for being set to mounting base;The guide rail be equipped with guide pad, the guide pad include upper guide section, lower guide section and It is located in the middle changeover portion, the outer diameter of the changeover portion and the internal diameter of location hole are identical, and the outer diameter of the upper guide section is by transition Section is gradually tapered to identical as guide rail outer diameter upwards;The outer diameter of the lower guide section be gradually tapered to downwards by changeover portion with Guide rail outer diameter is identical;The guide pad height is adjustably connected on guide rail.
By using above-mentioned technical proposal, when mounting base falls above guide pad, due to the outer diameter of changeover portion and fixed The internal diameter in position hole is identical, and the outer diameter of upper guide section is gradually tapered to identical as guide rail outer diameter upwards by changeover portion;Lower guide section Outer diameter be gradually tapered to downwards by changeover portion it is identical as guide rail outer diameter;Sliding seat carries out during contacting with upper guide section Position adjustment is adjusted completely to vertical direction so that dropping hammer until the inner wall of location hole is bonded with changeover portion;Work as sliding Seat with drop hammer continue to fall to location hole and lower guide section to it is corresponding when due to location hole internal diameter greater than lower guide section outer diameter And it is greater than the outer diameter of guide rail, it drops hammer and mounting base is in free falling body state, do not generate rail friction power in dropping process.Due to The height of guide pad can show that the distance that sliding seat is higher than changeover portion can also be obtained by measurement by measurement.By this Distance and the quality dropped hammer can calculate the practical increased gravity g1 of this test under no external force, if sliding seat exists Contact so as to adjust position with upper guide section in dropping process and consumed certain function, this test is practical to be increased The gravity g2 added is still less than above-mentioned gravity g1, as long as therefore referred to using detectable g1 as error, so that it may advise Keep away the friction effects generated when whole guide rail rubs with sliding seat.Compared with prior art, it is more conducive to reduce guide rail Influence of the frictional force to test result.
The present invention is further arranged to: screw rod is coaxially equipped in the guide rail, the both ends of the screw rod are rotationally connected with Rack, the guide rail are equipped with the vertically disposed sliding slot for guide pad sliding, and the guide pad is bolted in screw rod, the screw rod It is connected with the first driving motor.
By using above-mentioned technical proposal, drive screw rod rotation guide pad can be driven along cunning by the first driving motor Slot sliding, so that the height to guide pad is adjusted.
The present invention is further arranged to: first driving motor is connected with output shaft, coaxially connected on the output shaft There are two first bevel gear, the screw rod upper end in two guide rails is connected separately with a second bevel gear, each first cone Gear respectively with second bevel gear engaged transmission.
By using above-mentioned technical proposal, the first driving motor can drive two screw rods to rotate synchronously, so that two silks The synchronous progress of guide pad height adjustment on bar.
The present invention is further arranged to: the drop hammer lifting mechanism includes sliding seat and the folder that drops hammer that is installed on sliding seat The lifting device holding device and being connect with sliding seat;The rack is respectively provided with a vertically disposed cunning in the two sides of sliding seat Rail, the sliding seat are slidably connected to sliding rail, and the sliding seat is equipped with the through-hole passed through for guide rail, and the internal diameter of the through-hole is greater than The outer diameter of the changeover portion of guide pad, the through-hole and guide rail are coaxially disposed.
By using above-mentioned technical proposal, through-hole is greater than the outer diameter of changeover portion with guide rail coaxial arrangement and through-hole internal diameter, makes Sliding seat when being slided up and down along sliding rail, do not contacted directly with guide pad, to avoid interfering with each other.
